Abstract: A device or method selects information items from a plurality of information items which are emitted by transmitters located at a distance from a vehicle, with a view to transmitting the selected information items to at least one system on board the vehicle. The method includes: a) estimating the position of each information item on a map of movement paths in accordance with the absolute position of the information received, b) determining at least one place of interest at which to position the information items which the at least one on-board system wishes to have transmitted, c) selecting, from the information items received, the ones to transmit to the on-board system in accordance with their estimated position on the map and the place of interest.

Abstract: A piece of mobile vehicle equipment includes a V2X communication management device connected to a cellular communication network. The communication management device includes a Radio Access Technology selection unit that determines the Radio Access Technologies (RAT) available to be used for transmitting a data packet, associated with a V2X application executed by the piece of mobile vehicle equipment, to at least one receiving device. The selection unit selects the available Radio Access Technologies from a set of Radio Access Technologies, depending on target Quality of Service information including an n-tuple of performance indicators, the n-tuple of performance indicators including at least one performance indicator and being determined from a set of performance indicators chosen according to the V2X application.
